Convert them all to the same per x hours and then compare them. You can either convert them all to unit rates (x = 1) or some other rate (eg lcm of 16, 50, 15 and 20).
I'll use unit rates:
800 miles per 16 hours = 800 ÷ 16 miles per 16 × 16 hours = 50 mph
1500 miles per 50 hours = 1500 ÷ 50 miles per 50 ÷ 50 hours = 30 mph
600 miles per 15 hours = 600 ÷ 15 miles per 15 ÷ 15 hours = 40 mph
900 miles per 20 hours = 900 ÷ 20 miles per 20 ÷ 20 hours = 45 mph
50 mph is the greatest unit rate
→ 800 miles per 16 hours is the greatest rate.
---------------
The rates can be ordered:
50 > 45 > 40 > 30
→ 800 miles per 16 hours > 900 miles per 20 hours > 600 miles per 15 hours > 1500 miles per 50 hours.
Write each rate as a unit rate 70 miles in 2 hours
Distance = Rate * Time or, for our purposes, Rate = Distance/Time Rate = 200 miles/4 hours = 50 miles per hour ==============
Unless you know the rate the miles can not be derived from miles.
420 miles in 7 hours is 60 MPH (miles per hour).
Distance = Rate * Time or, algebraically manipulated for our purposes Time = Distance/Rate Time = 212 miles/70 mph = 3.0 hours ----------------

To get the rate for 250 miles in 5 hours, divide the miles by the hours to get miles per hour, 250 miles/5 hours=50 miles per hour. If you divide 5 hours by 250 miles, you get 0.02 hours per mile, the other unit rate for this set of numbers.
To find out how many miles Dan would drive in 5 hours, first determine his driving rate. He drove 605 miles in 11 hours, which gives a rate of approximately 55 miles per hour (605 miles ÷ 11 hours). At that rate, in 5 hours, he would drive about 275 miles (55 miles/hour × 5 hours).
To find the rate at which Nicole is driving, divide the total distance by the total time: 804 miles / 12 hours = 67 miles per hour. To determine how many miles she would drive in 7 hours at this rate, multiply her rate by the new time: 67 miles per hour x 7 hours = 469 miles. Therefore, Nicole would drive 469 miles in 7 hours at the same rate.
Divide the number of miles by the number of hours to obtain the unit rate. You should get: 128 miles / 2 hours = 64 miles per hour
Write each rate as a unit rate 70 miles in 2 hours
Distance = Rate * Time or, for our purposes, Rate = Distance/Time Rate = 200 miles/4 hours = 50 miles per hour ==============
Distance = Rate * Time or, for our purposes Rate = Distance/Time Rate = 24986.73 miles/216.06 hours = 115.65 miles per hour -------------------------------
To find the unit rate of 180 miles in 3 hours, divide the total distance by the total time. So, 180 miles ÷ 3 hours = 60 miles per hour. Therefore, the unit rate is 60 miles per hour.
To find the unit rate, divide the total distance by the total time. For 60 miles in 2 hours, the calculation is 60 miles ÷ 2 hours = 30 miles per hour. Therefore, the unit rate is 30 miles per hour.
Distance = Rate * Time manipulated, Rate = Distance/Time Rate = 22 miles/2.5 hours = 8.8 miles per hour ===============
288 miles
